The spindle slide-to-gib clearance may need
adjusting so there is no play when pressure is
applied to the spindle. Gib adjustments are
made by loosening or tightening some or all of
the four setscrews on the side of the elevation
housing shown in Figure 31.
To check the spindle slide-to-gib clearance,
do these steps:
1. UNPLUG THE SHAPER!
2. Turn the handwheel until the spindle is in the
highest position.
3. Lock the spindle in place by tightening the
spindle lock handle on the side of the shaper.
4. Grasp and wiggle the top of the spindle to
see if there is side-to-side movement. If
there is movement, adjust the gib to remove
this play.
To adjust the spindle slide-to-gib clearance,
do these steps:
1. UNPLUG THE SHAPER!
2. Loosen the setscrew jam nuts.
3. Slowly turn the four setscrews. Alternate
between the top and bottom so the pressure
will be uniform.
4. Tighten the hex nuts while holding the
setscrews in position.
5. Recheck the spindle slide up and down
movement. No play should exist and the
spindle should move up-and-down smoothly.
It may take several attempts to adjust the
spindle slide-to-gib clearance to get the
spindle to move up and down smoothly.

NOTICE
The spindle lock keeps the spindle in a
fixed position during shaping operations.
Since cast-iron threads can strip, DO NOT
over-tighten the spindle lock.
NOTICE
If the handwheel is adjusted so the spindle
slide completely moves to the lowest
position, and the handwheel is forced
further past the stop, the gib can fall out of
place and bind the spindle slide on future
upward travel. To correct this issue if it
occurs, loosen the setscrews, and reposition
the gib, and adjust the spindle slide-to-gib
clearance as outlined to the right.
